Welcome @JellybeanMama and congrats on the surgery date!
I had two weeks off work but my job is computer-based so I've just been working from home since then. I'm a bit wary about carrying my laptop bag into the office (which includes a mile walk each way) and I didn't need to do it as work are happy for me to wfh, so it didn't seem worth pushing it. If I'd had to go in, I think it would be OK now. Similarly, I haven't driven yet as per my consultant's advice, but that's because I haven't really needed to rather than because I can't.
It's really hard to say for your situation as we all recover differently. Personally the work you describe would have been tough for me to do at 2 weeks though. So if you can take a little longer off to recover, it might be a good idea. Have you asked your surgeon/your work whether a longer sign off is possible given the nature of your work? Is there any possibility of carrying out "lighter duties" initially?
